Troubleshooting

Motor not providing assistance

Check if the battery is charged and properly inserted. Ensure the system is turned on and the correct assist level is selected. Verify that the speed sensor is clean and aligned.

Battery not charging

Ensure the charger is plugged in and the outlet is working. Check the battery and charger connections for dirt or damage. Consult the Bosch e-bike manual for specific troubleshooting steps.

Poor shifting performance

Clean and lubricate the drivetrain. Check for any damage to the derailleur or shifter. If the issue persists, the derailleur may need adjustment by a professional.

Tires losing air

If running tubeless, check for leaks around the rim tape, valve stem, or tire bead. Add more sealant if necessary. Inspect the tire for punctures.

Reduced range or power

Ensure the battery is fully charged. Check that tires are properly inflated. Reduce the level of motor assistance used. Extreme temperatures can also affect battery performance.

Setup, Compatibility & Care

Initial Setup: Upon receiving the Trek Marlin+ 8, it is recommended to have it assembled and inspected by a qualified bicycle mechanic. This ensures all components, especially the e-bike system, are correctly installed and adjusted.
